The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s cookin’ for the next 16 days. We’ve got one spot on the radar, and I gotta be straight with you—it’s a rough stretch.
Overall Pattern: Honestly, it’s gonna be a long, frustrating wait. The forecast is a real bummer for the first 12 days. We’re looking at a massive gap with no good surf on offer from now until around the 11th of August. The wind is just relentless, coming in strong from the east-northeast, keeping things chopped up and messy. The only real glimmer of hope comes way out on the horizon.
The Long Wait (28th July – 11th August): For the next two weeks, Kohala Lighthouse (Big Island) is the only game in town, but it ain’t a pretty one. The trade winds are just honking, 15 to 25 mph, mostly cross or cross-shore. That’s gonna turn any potential into a bumpy, wind-slop mess. We start with a solid 10 ft swell on Tuesday the 28th from the ENE, packing some serious energy (2610), but with those strong onshore winds, it’s just a washing machine. Swell sizes dip and rise through the week, but the wind never lets up. Even when the swell drops to a more manageable 4 ft on Wednesday morning the 29th, the wind is still ruining it. All the way through to the 11th, every single session is flagged as “poor surf conditions.” It’s a real dry spell, and for a place like this, a blank run of this length is more normal than you’d hope.
The One Standout (12th August): Okay, mark your calendars for Wednesday the 12th of August. We finally get a break in the wind. The morning is looking clean with a light cross-offshore breeze, and the swell is a modest 5 ft from the ENE. The wave energy is weak (243), but for the first time in the whole forecast, the conditions are actually “clean.” The period is short at 7 seconds, so it’ll be a bit of a weak, crumbly wave, but it will be rideable. This is the only time the score is anything above zero, and it’s the best on offer by a long shot. It’s a promising little window, but it’s a long way off, so keep your fingers crossed. For the rest of the day, the wind picks right back up, so it’s just that one morning window.
Bottom line: You’ve got 12 days of nothing. Then, maybe, a few hours of clean, small waves on the morning of the 12th. That’s your shot.
Rusty.
